1. Introduction and Objectives
Contract costing is a form of specific order costing applied to large-scale, long-term projects that typically span multiple accounting periods. This lesson introduces the structural features of contract accounting, aligning with infrastructure projects and capital asset construction.
 
2. Unique Characteristics of Contract Environments
  • Site-Based Performance: Work is typically executed on an external construction site provided by the client, rather than inside the company’s own factory.
  • Extended Time Horizon: Projects frequently take multiple years to complete, introducing complex multi-period revenue recognition considerations under financial accounting standards.
  • Sub-Contractor Integration: Specialist tasks (e.g., electrical grids, commercial plumbing) are often outsourced to sub-contractors. These external costs are charged directly to the main contract ledger.
  • High Proportion of Direct Costs: Because construction happens on-site, expenses that are typically treated as indirect factory overheads—such as site supervisor salaries, equipment rentals, and site electricity—are tracked as direct costs for that specific contract.
